Description

Technical Field

[0001] This utility model relates to the field of photovoltaic snow clip technology, and in particular to a snow clip with drainage and dust removal functions. Background Technology

[0002] Currently, residential photovoltaic (PV) power stations are experiencing strong growth. However, residential PV systems are typically installed on the rooftops of rural bungalows, presenting complex construction and operation / maintenance conditions. Improving the safety and power generation of these stations has become a key research focus for maintenance. PV modules are located outdoors, and the tilt angle of residential PV modules varies depending on the roof slope, generally ranging from 10° to 30°. In northern regions with heavy snowfall in winter, slopes exceeding 10° pose a significant risk of snowfall and personal injury. Currently, snow removal for PV modules is done manually, which is highly dangerous and inefficient on residential rooftops. There is currently no effective solution to address the risk of snowfall.

[0003] A snow-blocking clip structure with drainage function is disclosed in Chinese patent CN222953984U. This snow-blocking clip structure, by setting an arc-shaped water-guiding buckle and a drainage hole, allows the water on the glass panel to melt. The water-guiding buckle can break the surface tension of the water, allowing the water to pass smoothly over the frame without accumulating on the glass panel, and then drain out through the drainage hole. This effectively prevents snow water from accumulating under the photovoltaic module, reduces the soaking of water on the back insulation material of the photovoltaic module, and reduces the risk of leakage that may be caused by this.

[0004] However, compared with existing technologies and solutions, this snow clip structure still has the following problems in actual use: After snowfall, the electrothermal activity of photovoltaic modules accelerates melting. Due to the low angle of some roofs and the raised structure of the module frames, snowmelt cannot flow completely off the frames, easily accumulating at the bottom edges. Mud and impurities washed down by the snowmelt settle in these puddles, forming mud streaks that cause localized shading and severely impact power generation. Furthermore, these mud streaks can only be addressed after the snow melts; the longer they remain, the greater their impact on power generation. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a snow clip with drainage and dust removal functions.

[0006] The purpose of this utility model is achieved through the following technical solution: a snow-blocking clip with drainage and dust removal function, including a photovoltaic module clamp, a drainage and dust removal pad and a photovoltaic module snow-blocking clip are provided on the top of the photovoltaic module clamp, and an adjustment wrench is fixedly connected to the top of the photovoltaic module snow-blocking clip. The bottom of the photovoltaic module clamp is equipped with fastening bolts, and the top of the photovoltaic module clamp is provided with a first adapter groove, a slot and a limiting groove; A second adapter groove is provided in the middle of the top of the drainage and dust removal pad, a connecting hook is provided on one side of the bottom of the drainage and dust removal pad, and a triangular groove is provided at the bottom of the drainage and dust removal pad. The photovoltaic module snow-blocking clip includes a connecting plate, a hook fixedly connected to one side of the connecting plate, and a baffle fixedly connected to the side of the connecting plate away from the hook.

[0007] Preferably, the adjusting wrench is compatible with the fastening bolt, and the adjusting wrench is fixedly connected to the top of the baffle.

[0008] Preferably, the second adapter slot is adapted to the first adapter slot.

[0009] Preferably, the drainage and dust removal pad is installed at the frame of the photovoltaic module, and the connecting hook contacts the bottom of the glass panel inside the frame of the photovoltaic module.

[0010] Preferably, the lower side of the drainage and dust removal pad, the inner side of the connecting hook, and the triangular groove are all made of hydrophilic polymer material.

[0011] Preferably, the hook has a snap-fit ​​structure and is engaged in the slot through a limiting groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This snow clip, equipped with drainage and dust removal functions, can block snow accumulation, preventing it from sliding down and damaging property in the yard or injuring passersby. When the snow is thick and the roof's snow load capacity is insufficient, it facilitates snow removal operations. After the snow melts, it flows down along the photovoltaic modules. When water accumulates under the photovoltaic modules, due to the angle of the photovoltaic modules, the water can form a siphon effect at the frame of the photovoltaic modules by relying on its own weight, the capillary effect of water, and the properties of hydrophilic materials, causing the water to flow out continuously and avoiding the formation of water or mud, thereby avoiding affecting the power generation of the photovoltaic modules.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0019] like Figure 1 As shown, a snow-blocking clip with drainage and dust removal functions includes a photovoltaic module clamp 1. The top of the photovoltaic module clamp 1 is provided with a drainage and dust removal pad 2 and a photovoltaic module snow-blocking clip 3. The drainage and dust removal pad 2 is made of semi-transparent anti-corrosion resin material and an anti-aging agent is added to increase its service life. An adjustment wrench 4 is fixedly connected to the top of the photovoltaic module snow-blocking clip 3. like Figure 2 and Figure 3 As shown, a fastening bolt 101 is provided at the bottom of the photovoltaic module clamp 1. An adjusting wrench 4 is adapted to the fastening bolt 101. The adjusting wrench 4 can be used to fasten or install and disassemble the photovoltaic module clamp 1. The adjusting wrench 4 and the photovoltaic module snow-blocking clamp 3 are an integral structure, which is easy to disassemble together with the photovoltaic module snow-blocking clamp 3. A first adapter groove 102, a slot 103 and a limiting groove 104 are provided on the top of the photovoltaic module clamp 1. like Figure 1 , Figure 4 and Figure 5 As shown, a second adapter groove 201 is provided in the middle of the top of the drainage and dust removal pad 2. The second adapter groove 201 is adapted to the first adapter groove 102. In use, the bottom of the photovoltaic module clamp 1 is close to the lower side of the photovoltaic module frame, and the side of the photovoltaic module clamp 1 is close to the side of the photovoltaic module frame. The second adapter groove 201 is pressed on the first adapter groove 102 and then clipped onto the upper side of the photovoltaic module frame. Tightening the fastening bolt 101 can fix the photovoltaic module clamp 1 to the photovoltaic module frame. A connecting hook 202 is provided on one side of the bottom of the drainage and dust removal pad 2. The drainage and dust removal pad 2 is located at the frame of the photovoltaic module. The connecting hook 202 directly contacts the bottom of the glass panel inside the photovoltaic module frame. A triangular groove 203 is provided at the bottom of the drainage and dust removal pad 2. The inner side of the connecting hook 202 and the triangular groove 203 are both made of hydrophilic polymer materials. During use, the capillary effect of water and the properties of the hydrophilic material are used to guide the snowmelt water from the connecting hook 202 into the gap between the triangular groove 203 and the photovoltaic module frame. The triangular groove 203 is perpendicular to the photovoltaic module frame, with one side extending into the inner side of the photovoltaic module frame and contacting the outer edge of the water, thus breaking the surface tension of the water. This allows the water to flow out along the gap between the triangular groove 203 and the photovoltaic module frame. Due to the angle of the photovoltaic module, the water can form a siphon effect at the photovoltaic module frame by its own weight, the capillary effect of water, and the properties of the hydrophilic material, causing the water to flow out continuously. The drainage and dust removal pad 2 has a semi-transparent structure, which makes it easy to observe whether there are any blockages in the triangular groove 203, thus facilitating timely cleaning. like Figure 1 and Figure 6 As shown, the photovoltaic module snow-blocking clip 3 includes a connecting plate 301, a hook 302, and a baffle 303. The hook 302 is fixedly connected to one side of the connecting plate 301. The hook 302 has a snap-fit ​​structure and is engaged in the slot 103 via a limiting groove 104, preventing the photovoltaic module snow-blocking clip 3 from loosening and falling off when subjected to external forces such as strong winds. The baffle 303 is fixedly connected to the side of the connecting plate 301 away from the hook 302. An adjusting wrench 4 is fixedly connected to the top of the baffle 303. Both the connecting plate 301 and the baffle 303... Made of aluminum alloy, the baffle 303 and the adjusting wrench 4 together form the facade structure. In winter, after the snow falls, the baffle 303 and the adjusting wrench 4 act directly on the side of the snow to block it. Since the snow particles have a large friction with each other, as long as the snow is blocked from falling from the component, it will not fall again even if it exceeds the top of the adjusting wrench 4. The connecting plate 301 connects the baffle 303 and the hook 302 and bears the horizontal snow stress and vertical snow pressure. The hook 302 is made of stainless steel, which is highly elastic and not easily deformed.

[0020] The work process is as follows: S1. After summer rains, rainwater and dust mixed with accumulated water can be discharged in time through the drainage and dust removal pad 2 to avoid the formation of mud belts, improve power generation, and prevent the formation of heat and hot spots on the underside of photovoltaic modules due to mud belts blocking heat generation. S2. The winter photovoltaic module snow clip 3 can block snow accumulation and prevent snow from sliding down and damaging items in the yard or injuring passersby. When the snow accumulation is thick and the roof snow load is insufficient, a long pole can be used to push against the side of the baffle 303 in a safe position to push the connecting plate 301, so that the hook 302 can be disengaged from the slot 103 and the limiting slot 104, and the snow can slide down smoothly for snow removal. The photovoltaic module snow clip 3 can be recycled and reused as it slides down with the snow. S3. After the snow melts, it flows down along the photovoltaic module and accumulates water on the underside of the photovoltaic module. Due to the angle of the photovoltaic module, the water can form a siphon effect at the frame of the photovoltaic module by relying on its own gravity, the capillary effect of water, and the properties of hydrophilic materials, so that the water can flow out continuously and avoid the formation of water or mud. The drainage and dust removal pad 2 has a semi-transparent structure, which makes it easy to observe whether there are any blockages in the triangular groove 203, so as to facilitate timely cleaning. S4. During photovoltaic inspection, especially during inspections in sudden strong winds, the adjusting wrench 4 can be used to tighten the photovoltaic module clamp 1 to improve inspection efficiency. S5. When the photovoltaic module is damaged and needs to be replaced, the photovoltaic module clamp 1 can also be disassembled using the adjusting wrench 4.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
